TEKS Related to the Lesson

(12) Organisms and environments. The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function. The student is expected to:

(C) recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms;

(D) differentiate between structure and function in plant and animal cell organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole;

Rationale

Students need to understand the structure of the cell in order to fully understand what are bodies are made up of. We are entirely made of cells just like the majority of the other organisms around us. Cells are a building block of living things and are an extremely important topic in life science.

Cells

Cells are the building blocks of many living things. We will study to major types of cells, animal and plant cells. Cells contain many different organelles that have a specific function to help the cell survive.

Lysosome

Return to Animal Cell Return to Plant Cell

Lysosomes are the digestion centers for the cell. They are common in animal cells, and rare in plant cells.

Nucleus

Return to Animal Cell Return to Plant Cell

The nucleus contains the cells DNA and is sometimes known as the brain of the cell.

Cytoplasm

Return to Animal Cell Return to Plant Cell

The cytoplasm is made up of cytosol. It is the jelly­like substance inside the cell that all of the organelles float in. The cytoplasm is not an organelle.

Mitochondrion

Return to Animal Cell Return to Plant Cell

The mitochodrion provides the cell with energy. It is sometimes called the power­house of the cell.

Cell Membrane

Return to Animal Cell Return to Plant Cell

The membrane is responsible for protecting the cell. It is made up of layers of lipids. The membrane also controls the entry and exit of materials from the cell.

Rough Endoplasmic Reticulum

Return to Animal Cell Return to Plant Cell

The rough endoplasmic reticulum is covered with ribosomes that synthesize proteins. The endoplasmic reticulum is a surface for chemical activity.

Smooth Endoplasmic Reticulum

Return to Animal Cell Return to Plant Cell

The smooth ER plays different roles in many cells. It usually is used as a surface for different chemical activity in the cell.

Golgi Aparatus

Return to Animal Cell Return to Plant Cell

The golgi aparatus is a stack of membrane bound vessicles that store and release chemicals waiting for transport around the cell.

Cell Wall

Return to Plant Cell

The cell wall is a strong barrier around plant cells. The cell wall helps the plant maintain its shape.

Vacuole

Return to Plant Cell

Vacuoles are rather large in plant cells and store water, waste and nutrients. The vacuole could also be known as the warehouse of the cell.

Chloroplast

Return to Plant Cell

Chloroplasts are found only in plant cells. They contain chlorophyll responsible for the green color of most plants. The food for a plant is made in the chloroplasts.

CentrioleCentrioles are part of the cytoskeleton of the cell. The centrioles help the cell to divide. Cetrioles are only found in animal cells.
