Cell Structures and Functions

Cell

• Basic unit of all forms of life.

• Basic unit of plant life

• Structures in living things that combine to make other cells

• Structure made of organelles that controls life functions

Cell Theory States That

• 1. cells are the basic units of structure and function in living things

  2. all living things are composed of cells

  3. All new cells are produced from existing cells.

• 1. cells are the basic units of structure of most living things

  2. Most living things are composed of cells

  3. All new cells are produced from existing cells.

• 1. cells are the basic units of structure and function in living things

  2. all things are composed of cells

  3. All new cells are produced from dead cells.

• 1. cells are the basic units of structure for all things in nature

  2. Living cells use energy

  3. All cells reproduce

Cell Membrane

• Thick wall that supports plant cells

• Thin barrier that makes energy for the cell

• Thin barrier that surrounds all cells and controls what enters and leaves the cell.

• The control center of the cell

Nucleus

• Makes energy for the cell

• Powerhouse of the cell

• Makes ATP

• The structure that contains the cell's genetic material in the form of DNA.

Eukaryote

• Unicellular organism that lacks a nucleus.

• Organism whose cells contain a nucleus.

• Organism that has no cell membrane

• A primitive autotrophic cell with no DNA

Prokaryote

• Unicellular organism that lacks a nucleus.

• Organism whose cells contain a nucleus.

• Organism that has no cell membrane

• A primitive autotrophic cell with no DNA

Cytoplasm

• Makes energy for the cell

• Cell organelle that digests waste and used up parts of the cell so the materials can be reused by the cell.

• Organelle that stores materials such as water, salts, proteins, and carbohydrates. Plants have big Vacuoles

• The fluid that fills the spaces inside a cell. All organelles float in the cytoplasm

Organelle

• Structure in eukaryotic cells that performs specific cellular functions necessary for life.

• A small organ

• Large area of storage in plant cells

• A group of similar tissues that perform a function

Vacuole

• Organelle that digests wastes, and carbohydrates. Plants have big Vacuoles

• Cell organelle that digests waste and used up parts of the cell so the materials can be reused by the cell.

• Structure in an animal cell that helps to organize cell division.

• Organelle that stores materials such as water, salts, proteins, and carbohydrates. Plants have big Vacuoles

Lysosome

• Organelle made of many folded membranes that helps produce, fold and transport proteins. Sometimes compared to a system of roads for transport.

• Cell organelle that digests waste and used up parts of the cell so the materials can be reused by the cell.

• Structure in an animal cell that helps to organize cell division.
