Cell Structures Or: how organelles work together to carry out life

functions

What is an organelle?

An organelle is a structure within a cell that carries out a specific function that supports the life of the cell and, consequently, life of an organism.

What are some functions of the organelles?

Bring in nutrients Remove waste Generating and releasing energy Making substances that the cell

needs Reproducing Regulating cell processes

Organelles in plant cells vs. organelles in animal cells

Think about the structure and function of plants and animals.

Do you think their respective cells would be same or different?

Cell Membrane

Separates the inside of the cell from the external environment and controls the flow of materials in and out of the cell.

Cytoplasm

Inside of the cell, contains sugars, water and other life supporting substances. Also, contains all the organelles.

Mitochondria

Energy is released from glucose (sugar) to fuel cell activities.

Endoplasmic Reticulum

A network of channels that help transport materials made in the cell. Connected to the nucleus.

Golgi Body

Sorts and packages proteins and other molecules for transport out of the cell.

Nucleus

Controls all cell activities.

Vacuoles

Contain water and other materials. Also aid in maintaining structure and transporting small molecules.

Cell Wall (plants only)

Tough and rigid. Outside cell membrane. Supports the cell.

Chloroplast (plants only)

Traps energy from the sun makes glucose (photosynthesis) glucose broken down in mitochondria powers cell activities.
