MODULE 3: CELL

cell

basic unit of life

organelles

specialized structure in cell that perform specific functions

membranous cell organelles

it is important for metabolic activity in the cell surrounded by unit membrane.

non-membranous cell organelles

not surrounded by unit membrane

cell membrane

also called fluid mosaic model; made of phospholipids and proteins

cell wall

provides protection, give cell strength and structure, filter molecules that pass in and out. Compose of cellulose, pectin, and suberin.

cytopplasm

gel-like fluid that fills the cell and keep the organelles in place.

mitochondria

power house of the cell; breakdown food molecules and turn out ATP (energy)

Golgi Apparatus

helps in processing, packaging, and transferring lipids and protein.

endoplasmic reticulum

interconnected flattened sacs that delivers synthesize proteins.

ribosome

cell’s protein factory

plastids

round, oval, or disk-shaped bodies found in the cells of green plants.

chromoplast

plastids that is found in flowers and fruits.

chloroplast

plastids that is found in leaves which also carry out photosynthesis.

grana

site of conversion of light energy to chemical energy

microtubules

gives structural support; compose of cilia and flagella.

lysosomes

suicidal bag; destroy foreign bodies.

nucleus

center of the cell and houses of DNA.

nuclear membrane

located at the edge of nucleus

nuclear pore

located at the surface of nucleus where the materials pass in and out of nucleus.n

nucleolus

produces ribosomes

chromosome

made of DNA and proteins; part id genetic make up.

chromatin

this is loosely coiled chromosome

inclusions

non-living structure presents within the living cell.

vacuole

responsible for storage, waste disposal and growth. It is a watery compartment.

flavones

water soluble that gives yellow color

anthocyanin

pigment that gives red color.

leucoplast

a colorless plastids that is responsible for storage.

amyloplast

plastids involve in storing starch

elaioplast

plastids that is involve in fats and oil.

aleuroneplasts

plastids responsible for protein
