CELLS

Basic structural and functional unit of all living things.

3 Major cellular regions

also called as cell membrane

Forms the outer boundary of the cell

Located centrally, directs cell activities

most cell activities happens in, it is located between the plasma membrane and nucleus

Specialized structures perform specific functions

4 functions of the cell

It functions as boundary separating the intracellular/extracellular substances

It is a result of the cells regulation of ion movement

before the nucleus

oldest living organism, smaller and simpler in structure

has a nucleiod and is not bounded by a membrane; do not have membranous organelles

true nucleus

with nucleus bounded by membrane and contains other membrane-bound organelles

two types of eukaryotic cell

difference of plant and animal cells

composed of double layer of phospholipids and proteins that controls what enters of leaves the cell

has heads and tails that makes up a bilayer

what part of phospholipids that contains glycerol and phosphate which attracts water or ____

what part of phospholipids that are made up of fatty acids and are water fearing or ____

In 1665, he used a microscope to examine a thin slice of cork

True False

These proteins are attached on the inner or outer surface

These proteins are embedded completely through the membrane

This lies immediately against the cell wall in plants cells

Function of cell membrane in plants

This is found outside of the cell membrane, nonliving layer

Function of cell wall

TRUE OR FALSE
Cell wall are living layer of the cells
True False

It is a jelly-like substance enclosed by a cell membrane

this helps maintain cell wall in animals

Help move organelles and are made of proteins

these are threadlike and made of ACTIN

these are tubelike and made of TUBULIN

It is found only in animal cells, a paired structure near nucleus
