BIOL PLANT TERMS

Amyloplasts

chloroplast are storage, storage sugar

parenchyma cells

support cells

Pericycle

responsible of making xylem and phloem, making cells

Epidermis

covers the entire root

Apical meristem

at the end of the root cap, primary growth

Root mucliage

mucus like subtance

axillary Bud

branching can occur, if damaged the buds can start growing and contain cells that can become apical meris

Vascular bundles

surrounds the pit in a dicot stem, has xylem, phloem, and fiber, looks like candy corn

Fibers

allows the stem to stand up right

Sclerenchyma Fiber

give strength to the stem

Collenchyma

add flexibility and is surrounded by the epidermis cells

Woody Dicot

Center has the pith that has sugar and storage, xylem is where you measure the tree rings, outside the phloem are the periderm cells

Non-woody dicot

does not have rings

Monocot stem

scattered vascular bundles

mesophyll cells

contains chlorophyll, the cells on top will have more chloroplast

Palisade Mesophyll cells

Long columns of cells under the upper epidermis

Spongy mesophyll cells

at the bottom and scattered, allow gas exchange

Veins of the leaf

Vascular bundle

Waxy cuticles

prevent the loss of water, at the top of the leaf

Stoma

gas opening on the bottom of the leafs, surrounded by guard cells

Guard cells

open and close for gas exchange and water loss
