Cells

Carbohydrate

An energy-rich organic molecule of carbon, hydrogen, and oxygen, like sugar or starches. Carbohydrate. Carbohydrates are molecules that provide energy for our body, primarily found in foods like bread and fruits.

Cell

The basic unit of life. Cell. A cell is the smallest living unit that makes up all organisms, containing the necessary components to sustain life.

Cell membrane

The cell boundary that controls what enters and leaves the cell. Cell membrane. The cell membrane is like a protective barrier that surrounds the cell, deciding what substances can go in or out.

Cell theory

Cells make up all organisms, are the basic units of life, and come from other cells. Cell theory. Cell theory states that all living things are made of cells, which are the fundamental units of life, and new cells are produced from existing cells.

Cell wall

The rigid structure around a plant cell that supports and protects it. Cell wall. The cell wall is like a tough outer shell that helps keep plant cells in shape and safe.

Chloroplast

The plant organelle that uses light energy to make food. Chloroplast. Chloroplasts are tiny structures in plant cells that capture sunlight to help make food through photosynthesis.

Cytoplasm

A jellylike material in a cell. Cytoplasm. It is the gel-like substance inside a cell that holds all the cells components and is where most cellular activities occur.

Cytoskeleton

The protein network that controls the cell's shape and movement. Cytoskeleton. The cytoskeleton is a structure inside cells that helps maintain their shape and aids in movement.

Endoplasmic reticulum

The membranes in a cell's cytoplasm that move proteins. Endoplasmic reticulum. It is like a factory inside the cell that helps produce and transport proteins and fats.

Eukaryote

A cell that has a membrane and nucleus. Eukaryote. A eukaryote is an organism whose cells have a nucleus enclosed within a membrane.

Function

The special, normal, or proper activity of an organ or part. Function. In Science, function refers to the specific role or job that something performs in a system.

Golgi body

The cell structure that packages materials for transport within and out of the cell Golgi body. The Golgi body is like the cell's post office, where proteins and lipids are sorted and sent to their destinations.

Homeostasis

The maintenance of the stable internal conditions in an organism. Homeostasis. It is how living things keep everything inside them steady and balanced, like temperature or pH levels.

Lipid

An energy-rich organic compound such as a fat or oil. Lipid. Lipids are molecules that store energy and make up the cell membranes in living organisms.

Lysosome

A cell organelle that contains digestive enzymes. Lysosome. Lysosomes are small structures in cells that break down waste and unwanted material using enzymes.

Mitochondrion

The cell organelle that releases energy from food molecules. Mitochondrion. The mitochondrion is the power center of the cell, converting food into energy the cell can use.

Multicellular

An organism that is made up of many cells, like all animals, plants, and fungi. Multicellular means having multiple cells working together to form a living organism.

Nucleic acid

A molecule made of nucleotides that contain genetic material, like DNA and RNA, is called nucleic acid. Nucleic acids are molecules that store and transmit genetic information in cells.

Nucleus cell

The control center of a cell. Nucleus. The nucleus is like the brain of the cell, where it stores and manages the cell's genetic information.

Organ

A group of tissues that work together to perform a function, like the heart, liver, or stomach, is called an organ. An organ is a part of the body that performs a specific job essential for survival.

Organ system

A group of organs that work together to perform a specific function, like the digestive system. Organ system. An organ system is a collection of organs that collaborate to carry out a particular task in the body.

Organelle

A structure in a cell, specialized to perform a specific function. Organelle. An organelle is like a tiny organ inside a cell that helps it work properly.

Organism

Any living thing. Organism. An organism is a living entity that can grow, reproduce, and respond to its environment.

Protein

An organic compound that is made of amino acids. Protein. Proteins are essential molecules that help build and repair tissues in living organisms.

Ribosome

A small cell structure that builds proteins. Ribosome. A ribosome is a tiny machine inside cells that links together amino acids to make proteins.

Structure

The parts of an organism as a whole. Structure. In science, structure refers to how something is organized or arranged.

Tissue

A group of similar cells working together to perform the same function. Tissue. Tissue is a collection of cells that work together to carry out a specific role in the body.

Unicellular

An organism made of a single cell. Unicellular. Unicellular means that the entire organism is composed of just one cell, like bacteria.
