chapter 21.1 plant cells and tissues

the most common type of plant cell – stores starch, oils, and water
parenchyma cell
cells more commonly found in younger tissues of leaves. they are flexible and stretchy
collenchyma cell
the strongest basic plant cell. Has a second wall hardened by lignin
sclerenchyma cell
Plant tissues are made up of 3 basic types of “cells”
1. parenchyma cell
2. collenchyma cell
3. sclerenchyma cell
Plant organs are made up of 3 “tissue systems”
1. dermal
2. ground
3. vascular tissue
A plant tissue that covers the ouside of a plant and protects it
dermal tissue
plant tissue that is made up of parenchyma cells in the non woody parts of plants
dermal tissue
much of the inside of a plant that is surrounded by dermal tissue
ground tissue
provides support and stores materials in roots and stems
ground tissue
in leaves ground tissue is packed with
chloroplasts
photosynthesis makes food for the plant in the
chloroplasts
transports water, mineral nutrients, and organic compounds to all parts of the plant
vascular tissue
name the two networks of vascular tissue
1. xylem
2. phloem
the name for the vascular tissue that carries water and dissolved mineral nutrients from the roots to the rest of the plant
xylem
the name for the vascular tissue that carries the products of photosynthesis through the plant
phloem
