Male fern (UEB uncontracted)

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.

Limiting factors of photosynthesis (UEB uncontracted)

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.

Common hair cap moss (UEB contracted)

by Rnib

This is an image of a Common Hair-cap Moss (Polytrichum commune) sporophyte. This has grown from a zygote, the result of the fusing of male and female gametes on the green plant (gametophyte). The sporophyte remains attached to the green plant.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 moss is fixed in the ground at the bottom centre of the page. Going up from here there are narrow leaves growing out to the left and right from the stem. There are brown leaves at the bottom and green leaves further up.The stem continues up the page.You will find the plans capsule containing spores at the top of the image. It has a lid, with beak on top, which opens to release the spores; these will grow into new green plants.Like most mosses the Hair-cap grows in moist habitats: wet heathland or bogs. Its height ranges from 5 to 30 centimetres. Many plants will grow together to form a thick mat.
