Plant Cell Organisation

Question 1

Epidermal tissue?

Answer 1

covers whole plant.

Question 2

Palisade mesophyll tissue?

Answer 2

part of leaf that most photosynthesis occurs.

Question 3

Spongy mesophyll tissue?

Answer 3

part of leaf that contains large air spaces allowing gases to diffuse in and out of cells.

Question 4

Xylem and phloem?

Answer 4

transport water, mineral ions, food around the plant.

Question 5

Meristem tissue?

Answer 5

found at growing tips of shoots and roots and is able to differentiate into different types of plant cells allowing plant to grow.

Question 6

How are epidermal tissue structures related to their function?

Answer 6

covered with waxy cuticle which helps reduce water loss by evaporation.

Question 7

How is the structure of the palisade layer related to its function?

Answer 7

they’re near the top of the leaf so they have lots of chloroplasts where they can absorb the most light.

Question 8

How is the structure of the xylem and phloem related to its function?

Answer 8

these support the structure and also form a network of vascular bundles that deliver water and other nutrients to the leaf and take away glucose produced by photosynthesis.

Question 9

How are the tissues of leaves adapted to their function?

Examples?

Answer 9

for efficient gas exchange

e.g. lower epidermis is full of stomata which allow carbon dioxide to diffuse into the leaf.
