28 Cards in this Set

  • Front
  • Back
cell membrane
Regulates what enters or leaves the cell.
All cells have a cell membrane.
This outer boundary made of lipids, proteins, and carbohydrates.
Also called plasma membrane
cytoplasm
Everything between the cell membrane and the nuclear membrane.
(Liquid plus soilds)
cytosol
Liquid,jellylike, part of cytoplasm.
Includes: water, salts, proteins, fats, sugars.
cell wall
Supports and protects cell.

Nonliving, found in plants, bacteria, some protists, and fungi.
organelles
Part of a cell that carries out specific functiions for the cell.
They work like tiny organs (heart, liver) in our bodies.
cell
The smallest unit that can carry out all life functions.

Life processes include: reproduction, maintain homeostasis, respond to stimuli, etc)
nucleus
Control center of the cell.

Contains hereditary material (genetic material) your parents gave you.
nuclear membrane
regulates what enters or leaves the nucleus.

Double layered, has pores in it.
DNA
Hereditary material of cell.

Molecule that has the code of life on it.
mRNA
A copy of the DNA that directs organelles.
chromatin
Long strands (spaghetti like) of hereditary material in nucleus.

Hereditary material normally in long strands.
chromosome
Short chunky strands of hereditary material.

Chromatin shortens and folds up before a cell copies itself.
nucleolus
Area in nucleus were ribosomes and proteins are made.
mitochondria
Produce energy for the cell (ATP.

Mighty mito, powerhouse of the cell.
Lage surface area, folded membranes.
lysosome
Container for digestive enzymes inside the cell.
Made by the Golgi body, can digest small molecules or even whole cells.
ribosome
Site of protein synthesis.

Protein synthesis on the ribosome turns the food proteins you eat(amino acids) into your proteins.
vacuoles
Storage sac for food, water, or wastes inside the cell.
vesicle
Small vaculoes that move materials around the cell.
edoplasmic reticulum
Transports materials inside the cell.
Can be smooth (makes and transports fats) or rough (ribosomes attached, and moves proteins)
Golgi body
Packages and prepares proteins for cell use.

Works with ER in processing proteins and it makes lysosomes.
cytoskeleton
Maintains the cell shape, transports materials in the cell, and between cells.
chloroplast
Organelle that contains chlorophyll used in photosynthesis.
centrioles
Aids in cell division (animal cells).
What do we cal the medicine that can prevent but not cure a disease?
vaccine
What organelle would destroy old dead cell parts?
lysosome
Why do most AIDS victums die from secondary diseases?
The HIV destroys immune system to the point it cannot defeat other disease that are introduced into the body.
A microscope that maginfies a million or more times and the specimen must be dead.
TEM
Three ways plant cells differ from animal cells?
A. Cell walls
B. Chloroplasts
C. Larger vaculoes
