Science unit three cells and organisms Science unit three cells and organisms

Endoplasmic reticulum

Transports proteins throughout the cells

Golgi apparatus

Finishes sorts, labels, and ships proteins

Lysosome

Digest foods and cleans up and recycles worn out organelles

Vacuoles

Used to store, food, water, or waste

Mitochondria

Breaks down sugar molecules to make energy

Cell wall

Give shape protection, and gives supports to cell

Chloroplast

Uses energy from the sun to make food for the plant does the process of photosynthesis

Organelle

Specialized structures in cells which perform cellular functions and are only found in eukaryotic cells

cell membrane

Surrounds the cell only let certain materials in and out of the cell

Cytoplasm

All organelles are suspended in this and all life functions take place here

Nucleus

It controls all the cell functions, especially reproduction

Ribosome

It’s the site of protein synthesis proteins are made here using the DNA code from the nucleus

Plant cells have

Chloroplast

Cell wall

Large vacuum

Nucleus

Mitochondria

Cell membrane

Golgi apparatus

Cytoplasm

Animal cells have

Lysosomes

Small vacuoles

Nucleus

Mitochondria

Ribosome

Cell membrane

Golgi apparatus

Cytoplasm

What two parts do plant cells have that animal cells do not

They do not have a cell wall and chloroplast

Cell

Unit of structure and functions for all life

Tissue

Composed of groups of similar cells

Organs,

composed of groups of tissues functioning together

Organ systems

Compose groups of organs functioning together

Types of cells

Prokaryotes

Eukaryotes

Prokaryotes

They do not have organelles. Examples are bacterial cells.

Eukaryotes

They have organelles and examples are plant or animal cells

Cell theory

All living things are made of cells

Cells are basic unit of structure and function

New cells come from pre-existing cells

Exception to cell theory

Viruses are not living

Where did the first cell come from?

Mitochondria and chloroplast have their own genetics and can reproduce on their own yet they are organelles not cells

Metabolism

All chemical reactions that occur in an organism to make and use energy

Homeostasis

Maintaining a constant internal, condition, regardless of the external environment

Examples are shivering and sweating

Cellular respiration

Produces energy occurs in the mitochondria

Aerobic

Needs oxygen

Anaerobic

Does not need oxygen

Regulation

Control and coordination of life processes it allows the body to maintain homeostasis

Reproduction

Production of offspring

Asexual

One parent

Sexual

Two parents the charger

Growth and repair

To increase in size change over individuals lifetime gets bigger and matures

Excretion

Removal of metabolism, waste CO2 sweat water

Nutrition

All organisms get nutrients through food

Autotrophic

Make their own food through photosynthesis

Heterotrophic

Get nutrients from the environment

Transport

Organism circulate and absorb materials through the cells

Synthesis

To build or make something from small to large
