What are 3 adaptations of leaves for photosynthesis?

Answer 1

1 leaves have larger surface area so they can absorb light from sun

2 they are thin so light can pass into them easily

3 the cells of leaves have chloroplast which absorb light energy

Answer 2

Leaves have a large surface area, and a spongy layer allowing gases to diffuse easily in and out of the leaf, and it is well exposed to light. They are very thin which means CO2 and H2O don't have a large distance to travel. The Chlorophyll is in the top palisade layer closer to the light so it can absorb lots of light energy for photosynthesis. The upper epidermis is also transparent which also helps the light to reach the chlorophyll.

Answer 3

A leaf has a lot of chloroplast's, in the palisade cells, which is the second layer right under the upper epidermis

A leaf is naturally thin to allow efficient diffusion of substances such as carbon dioxide and water

The wax layer on top of the leaf is transparent. So that it protects the leaf without blocking any sunlight from reaching the palisade cells

Answer 4

1 leaves have larger surface area so they can absorb light from sun

2 they are thin so light can pass into them easily

3 the cells of leaves have chloroplast which absorb light energy

Answer 5

1.) arrangement of leaves on the stem such that they hardly shade one another

2.) thin and wide leaf blade

3.) numerous chloroplasts in the cells

4.) thin walls of leaf cells

5.) stomata

6.) air spaces in the mesophyll

7.) veins

8.) cutin

Answer 6

The leaf has a large surface area on the outside and inside of the leaf for maximum absorption of sunlight. On the surface of the leaf, the epidermis is clear like a window to allow light in. The cells within the leaf, the mesophyll, is arranged with a palisade layer vertical to the surface of the leaf which maximizes the chance the light will be absorbed by one of the hundreds of chloroplasts in the cell. The next layer, the spongy mesophyll has numerous space between the cells to allow gas diffusion, carbon dioxide, into the cells and the chloroplasts, movement of water and minerals into the cells and the escape of oxygen gas out of the leaf. The lower epidermis has numerous openings called stomata regulated with a pair of guard cells for gas exchange in and out of the leaf but can close if there is strong wind or lack of water that would harm the leaves.

Answer 7

The chloroplasts in the leaf cell absorb light energy to make food (photosynthesis).

Answer 8

The shape of leaf .the presence of chloroplast arrangement of tissues and presence of stomata on the lower surface helps the leaf to do photosynthesis
