Cells and Body Systems

An organism is a living thing made of cells.
Organs in the body are made of tissues, and tissues are made of cells.

Cell

Cells are the fundamental units of the body.
An organ is a structure in the body that has a specific function.
Skin is an example of an organ made of many cells.

Tissues

Tissues are groups of similar cells that perform a similar function.
Examples of tissues include muscle tissue, and connective tissue

Organs

Organs are structures in the body composed of different types of tissues.
Organs work together to perform complex functions.

Types of Animal Cells

Connective tissue cells support and connect different parts of the body (e.g., blood, cartilage, bone).
Epithelial cells cover the surfaces of organs and the body (e.g., skin).
Nervous tissue cells send signals throughout the body (e.g., brain, pain receptors).
Muscle tissue cells allow movement (e.g., skeletal muscle, heart muscle).

Single-celled Organisms

Some organisms (bacteria, viruses, algae) only need one cell to live and function.

Multicellular Organisms

Multicellular organisms (plants, animals) need many cells to carry out life functions.

Animal Cell Structure

Cell membrane: surrounds the cell, controls what enters and leaves
Nucleus: controls cell activities, contains DNA
Endoplasmic reticulum (ER): produces proteins
Ribosomes: make proteins
Mitochondria: produce energy for the cell
Vacuoles: store substances
Golgi complex: modifies and packages proteins

Plant Cell Structure

Cell wall: rigid outer layer providing support and shape
Chloroplasts: convert light energy into sugars (photosynthesis)
Vacuole: large storage space for water and other substances.

Cell Membrane Transport

Diffusion: movement of particles from high to low concentration.
Osmosis: movement of water from low to high solute concentration.
Active transport: movement of particles from low to high concentration using energy (ATP).

Cell Functions

Golgi complex: packages substances for transport
Mitochondria: energy production
Lysosomes: break down cellular waste

Test your knowledge on the basics of cells and how they form tissues and organs in the body. This quiz will cover various types of animal cells and their functions within different body systems. Challenge yourself with questions related to the fundamental units of life and their organization.
