Plant Adaptions and features of the plant

Question 1

Large surface area

Answer 1

Due to the competition of sunlight leaves need as much space to catch solar rays as possible

Question 2

Chlorophyll

Answer 2

A substance found in chloroplasts to help the process of photosynthesis

Question 3

Thin walls

Answer 3

To improve gas exchange

Question 4

Networks of vessels

Answer 4

Phloem and xylem transport glucose water and minerals around the plant

Question 5

Stomata

Answer 5

Pores which trap neccesary gases such as Co2 and release Oxgyen

Question 6

Transparent epidermis layer

Answer 6

Has no organelles so more sun light can pass through it

Question 7

Palisade layer at the top of the leaf

Answer 7

Closest to the surface to absorb as much sunlight as possible as this layer contains chloroplasts

Question 8

Xylem

Answer 8

Transporation of water and minerals. Hollow and dead. They control the movement of of water from the roots through the xylem and out of the leaves is called the transpiration stream

Question 9

Phloem

Answer 9

Transports glucose around the cell . Made of elongated cells with small pores to allow cell sap to run through .

The movement of cell sap through the leaf is translocation

Question 10

Spongy layer

Answer 10

Cells are spaced out allowing for more space for trapping gases

Question 11

How does stomata control gas exchange and water loss

Answer 11

When the plant has lots of water the guard cells fill and go turgid . This makes the stomata open so gases can be exchanged and allow photosynthesis to occur

When the plant is short of water the guard cells become flaccid and cause the stomata to close . This is too keep in as much water as possible
