Plant tissues and specialized cells

Question 1

What are the three types of plant tissues

Answer 1

• Dermal - Vascular - Ground

Question 2

Explain dermal tissue

Answer 2

Epidermal tissue is a thin layer of cells that protect the leaves, stem, and flower.
Root hair: extension of root epidermal tissue to increase the surface area for water and nutrient absorption.
Epidermal tissues create a waxy cuticle on the leaves to protect the leaves from water loss

Question 3

What are the 2 types of vascular tissues

Answer 3

• Xylem - Phloem

Question 4

Explain xylem

Answer 4

The xylem transfers water and nutrients from the root to the leaves.
A hollow tube connects the root and leaves.

Question 5

Explain Phloem

Answer 5

Transfers sugars created by photosynthesis, other chemicals, and hormones throughout the body

Question 6

Ground tissue

Answer 6

It’s composed of all the tissue and is in between the vascular and dermal tissue
In performs different functions in different parts of the plants
- In roots - stores carbohydrates
- in stem - it provides storage and support
- In leaves- It preforms photosynthesis

Question 7

What are meristematic cells

Answer 7

• They have the ability to differentiate into any specialized cell
• Only cell that will continue to divide throughout the life of the plant

Question 8

Where are meristematic cells located

Answer 8

• Apical meristem
  tissue is located at the tip of the root and shoot which allows the plant to grow longer (up and down)
• Lateral meristem
  tissue is located in the stem and roots which allow the plant to grow wider (side - side)

Question 9

What are guard cells

Answer 9

• Create an opening in the cuticle which allows the gases (CO2) to enter the leaves during the process of photosynthesis.
  The openings are called stomata.
  Stomata are usually located on the underside of the leaves to reduce water loss during the evaporation and allow the upper surface to be used for photosynthesis.
