Scientific Law
Describe "what" is going to happen during a scientific phenomenon (e.g. Newtons Law).
Scientific Theory
Explain "how" or "why" a scientific phenomenon happens (e.g. Cell Theory).
Cells are the basic units of and in living organisms.
Structure and Function.
All cells are produced from
Other pre-existing cells.
The flow of in living organisms occurs in cells.
Energy.
All cells have the same basic and structure.
Chemical composition
Cells contain hereditary information, DNA, that is passed on from one cell to another during
Cell Division.
Your body as you add more and more .
Grows, Cells
Your body produces more and more cells during .
Cellular Reproduction.
is a very important process that occurs during Cellular Reproduction.
Mitosis.
: a cell without a nucleus or any complex organelles.
Prokaryotic Cell.
: a cell with a nucleus and a complex internal structure.
Eukaryotic Cell.
: a tiny cell structure that carries out a specific function within the cell
Each organelle is specialized and does its own job.
They all work together as a team to help the cell function.
Organelle.
: the region between the cell membrane and the nucleus
All of the organelles are suspended in this clear, jelly-like substance.
Cytoplasm
: a cell structure that controls which substances can enter and leave the cell
outer covering that provides protection and support
"barrier with doors
Cell Membrane
: a cell structure that contains nucleic acids, the chemical instructions that direct all
the cell's activities
"brain" of the cell
contains (made of DNA + protein) which contain the "blueprint" for the organism
Nucleus, Chromosomes
Cells are the basic units of and in living organisms.
Structure and Function.
: a small, grain-like structure in the cytoplasm of a cell where proteins are made
proteins are the building materials for the organism.
Ribosome
: a structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
Golgi Body
: rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions
"powerhouse" of the cell
convert energy from food (GLUCOSE) into a form the body can use (ATP) through a process called CELLULAR RESPI
Mitochondria
: a sac inside a cell that acts as a storage area
stores food and water
NOT found in ALL animal cells
if present in an animal cell, there are a few small vacuoles
Vacuole
: a rigid layer of nonliving material that surrounds the cells of plants
the plant cell and helps plants stand upright
made of a special type of carbohydrate called
Cell Wall, Supports, Cellulose AKA Fiber
: a small, round cell structure containing chemicals that break down large food
particles into smaller ones
3 functions:
A) remove/recycle worn out parts
B) defend the cell against foreign invaders
C) break down large food molecules into smaller ones to b
Lysosome
: a sac inside a cell that acts as a storage area
plant cells typically have one very large vacuole
stores large amounts of water which causes food is stored here in a form called another carbohydrate
Vacuole, Turgor Pressure, Starch
: a structure in the cells of plants and some other organisms that captures
energy from sunlight and uses it to produce food
contain green pigment which allows plants to make their own food
energy from the sun is used in a process called
Chloroplast, Chlorophyll, Photosynthesis
: the process by which plants and some other organisms capture the energy in sunlight and use it to make food
takes place in .
Photosynthesis, Chloroplasts
: the process by which cells break down simple food molecules to release the energy they contain
takes place in .
Cellular Respiration, Mitochondria
: the basic unit of structure and function in living things
Cells
: a group of similar cells working together (muscle, blood, nerve, epithelial, connective)
Tissue
: groups of tissues working together to perform a specific function (heart, stomach, brain)
Organ
: a group of related organs performing a vital life function (cardiovascular system)
Organ System
: a living thing (human being)
Organism
