referring to a type of cell that lacks a nucleus and other membrane bound organelles
prokaryotic
Referring to a type of cell that contains a nucleus and other membrane-bound organelles.
eukaryotic
The central organelle of a eukaryotic cell that contains the cell’s DNA.
Nucleus
: A thin, flexible layer that surrounds and protects a cell or organelle.
membrane
The jelly-like substance that fills the cell and surrounds the organelles.
cytoplasm
Single-celled microorganisms that belong to the prokaryotic domain.
bacteria
Microorganisms that are similar to bacteria but have distinct characteristics and belong to a separate domain.
archaea
: Organelles responsible for generating energy in eukaryotic cells through cellular respiration.
mitochondria
Organelles found in plants and algae that carry out photosynthesis.
Chloroplast
Small organelles that synthesize proteins
ribosome
: A selectively permeable barrier that surrounds the cell, controlling the movement of substances in and out.
cell membrane
: The living content of a cell, including the cytoplasm and nucleus.
protoplasm
tissues in which cells actively divide. They are responsible for production of more cells
meristematic or embryonic tissues
tissues derived from the meristems that have already assumed various shapes and sizes
permanent tissue
found at the tips of shoots and roots
apical meristems
meristems that increase girth or diameter of the plant
lateral meristems
usually found in the vicinity of nodes
intercalary meristems
these are the most abundant of all the cell types FOUND IN ALMOST ALL MAJOR PARTS OF HIGHER PLANTS
Parenchyma
this tissue is composed of thick walled cells of uneven thickness
chollenchyma
characterized by cells that are thick and tough walled
sclerenchyma
this is the outermost layer of the cells found in all young plant organs
epidermis
serves as the outermost covering of old stems and old roots of woody dicot plants
cork
composed of secretory cells that produce hormones
secretory tissues
