Epiphytic bromeliad (UEB uncontracted)

by Rnib

This image shows an Epiphytic bromeliad growing on the branch of a tree. This is the Aechmea cylindrata variety, which can grow up to 50 centimetres high.There is a locator dot shown, which will be at the top left of the page when the image is the correct way up.You will find a tree branch going across the bottom of the page. Halfway along, the roots of the bromeliad are wrapped around it.Up from here are the plans long, pointed, green leaves growing up and out to the left and right. The plant stores the water that gathers in the overlapping leaf-base. At the top centre of the image is the bromeliads flower spike. It has individual flowers growing out to the left and right from a central stem. The flowers are magenta near the stem and pale blue at their tips.Bromeliads are native to South America. They include Pineapples and Spanish moss.

Four main plant groups (UEB contracted)

by Rnib

There are four images on this page showing an example of a plant from each of the four main plant groups. The main characteristics of each plant are listed to the left of its image. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. A moss is shown to the left of top centre of the page. At the top of the image is the sporophyte containing the spores that will be released to grow into new individuals. Down from this is the stalk with thin leaves growing to either side. The fern is shown on the top right. At the top of the image is one of its fronds with pinna (leaflets) growing to either side. Further down is the rhizome with a mass of small roots growing down from it. To the right of the rhizome you will find two curled-up immature fronds, ready to open up. There is a branch of a conifer shown to the left of bottom centre. Its stem goes from the top left to the bottom right of the image with shoots growing to either side. The needle-shaped leaves grow out from the shoots. Part of a flowering plant is shown on the bottom right. It is sprig of a mint plant with two flower heads with many florets (tiny individual flowers) at the top of the image. Down the page from this are three oval leaves with serrated edges, growing out to either side of the stem.

Limiting factors of photosynthesis (large print)

by Rnib

These pages show images of curved line graphs. It is a multi-page image set on three pages. There is a locator dot shown on each page, which will be at the top left when the image is the correct way up. Limiting factors of photosynthesis, light: This graph shows the effect of increasing the intensity of light has on photosynthesis. The Y-axis on the left of the page is the rate of photosynthesis and the X-axis going across the bottom of the page is light intensity. The data line goes from the origin at point A up and right in a curve. It levels out at point B and then goes horizontally right to point C. Limiting factors of photosynthesis, temperature: This graph shows the effect increasing temperature has on photosynthesis. The Y-axis on the left of the page is the rate of photosynthesis and the X-axis going across the bottom of the page is temperature in degrees Centigrade. The data line goes from near the origin up and right in a curve. It comes to a rounded peak and then falls sharply. Limiting factors of photosynthesis, CO2: This graph shows the effect of increasing the concentration of carbon dioxide has on photosynthesis. The Y-axis on the left of the page is the rate of photosynthesis and the X-axis going across the bottom of the page is carbon dioxide concentration. The data line goes from the origin at point A up and right in a curve. It levels out at point B and then goes horizontally right to point C.

Male fern (large print)

by Rnib

This image shows a Male fern (Dryopteris felis-mas) with rolled immature fronds (leaves), rhizome and roots.There is a locator dot shown, which will be at the top left of the page when the image is the correct way up.The plans roots are at the bottom of the page growing from the rhizome above.There are immature fronds growing up from the left part of the rhizome. They are coiled up in spirals and will unwind to develop into mature fronds like the one to their right.The mature frond grows up and right to the top right of the page. It has a central stem with individual leaflets (pinna) growing out and up to the left and right, getting smaller towards the top of the frond. These leaflets are made up of even smaller leaflets called pinnules. These are shown on this image as a serrated edge to the pinna.The fern is a primitive plant without flowers or seeds. It reproduces instead, by releasing spores from sporangia on the underside of its leaves; these are not shown.

This page shows an image of a small plant growing in the ground. There is a locator dot shown, which will be at the top left, when the image is the correct way up. The image is surrounded by a dashed line image border. The green leafy part of the plant is in the top half of the page and the root is in the bottom half of the page. The plans stem goes vertically up the middle of the page. It has three oval leaves on the left, one at the top forming the shoot, and four leaves on the right. Curved arrows indicate water loss as vapour from the leaves. A line going horizontally across the middle of the page represents the soil surface. Down from this the soil is shown in cross section so the roots can be found. As the root goes down the page it divides into smaller multiples of roots. Arrows show the root absorbing water from the soil.

This page shows three images of a sprouting bean. There is a locator dot shown, which will be at the top left, when the image is the correct way up. The root is to the left and the shoot to the right. In the middle is the rounded shape of the bean. The top image shows the bean when it has just been laid in a dark cupboard. The auxin hormone is evenly spread in the shoot and root. In the second image gravity has caused the auxin to accumulate in the lower half of the shoot and root. In the last image the root has grown more on the side with the least auxin causing it to bend down. The shoot has grown more on the side with the most auxin causing it to bend up. When the root and shoot are vertical the auxin is spread evenly and so the bending stops.

Poppy (UEB uncontracted)

by Rnib

There is flower on the left and a flower bud on the right of the page. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The image is surrounded by a dashed image border. The poppy flower head is in the top left of the page. It has two outer overlapping petals and two inner overlapping petals. In the middle of the flower head are stamens radiating out from the centre. The inner petal on the right has a black patch at its base. The other three petals will have a similar patch but they are not shown. The flower stem goes down the page to the bottom of the image. In the bottom centre of the page is a single leaf mainly to the right of the stem. The base of the leaf at the bottom is in front of the stem so a short section of stem is hidden. A second stem comes from the bottom right of the page and goes up to the right centre of the page. The stem curls left and down at the top, ending in a rounded hairy flower bud.
