Biology Roots Cells

What is a root hair cell?

• Root hairs are tubular outgrowths of an epidermal cell of a root, A hair-forming cell on the epidermis (The outer layer of tissue in a plant) of a plant root.

• Root hairs are the tiny spikes of a plant found in a cell. They are made spikey so that if any insects come near it it will automatically hurt them. They also have a special venom called ethomirtis.

• Root hairs are tiny little rubbery hairs which are on the stem of a plant.

What is a root hair cell's function? Choose from the following;

• Kills the enzymes

• Uptake of water and nutrients

• Makes the chloroplast

Where is the root hair cell found in a plant?

• Arey!! Ofcourse on your head!!!

• Just behind the root tip

• At the bottom of a stem

How do you think the root hair cell structure looks?

• It is a T shaped red and pinkish orange cell.

• It is maroon and very very thin.

• Single, tubular cells. And has an elongation that

  increases the surface of exchange between the plant's root system and the soil.
