mitochondria
they are tiny structures inside your cells that act like microscopic power plants. They take nutrients from the food you eat, break them down, and turn them into a specific kind of energy (called ATP) that the cell can use to function and stay alive.

cytosol | jelly like fluid that fills cell

What it's made of: It is mostly made of water, along with dissolved salts, nutrients, and proteins.
What it does: It gives the cell its shape, allows materials to float around and be transported, and serves as the site for many important chemical reactions. |
nucleus | controls cell
holds your DNA: The nucleus safely stores your genetic material. This DNA contains all the instructions that make you who you are.
It gives the orders: Because it has the blueprints, the nucleus tells the rest of the cell what to do, how to grow, and when it is time to divide to make new cells.

vacuole | stores water wastes and nutreints

They make food: Chloroplasts capture energy from sunlight and use it, along with water and carbon dioxide, to make food (sugar) for the plant. This amazing process is called photosynthesis.
They make plants green: Inside the chloroplast is a chemical called chlorophyll. Chlorophyll acts like a sponge for sunlight, and it is exactly what gives plant leaves their green color!

cell wall | acts as the cells protection
It sits on the very outside of the cell, wrapping around the softer, more flexible cell membrane.

cell membrain | filters what can come in and out of the cell
cell membrane is a soft, flexible layer. It is found on the outside of every single living cell—including all the cells in your body—holding everything inside together like a water balloon.

cell | makes up all living things |
photosynthises | converting sunlight to energy and nutrients. |
tissue | group of similar cells working together |
organ | group of tissues working together to perform a specialized job |
organ system | group of specific organs working together to perform a task |
organism | It is a single, individual living thing. It represents the culmination of all those smaller parts—cells, tissues, organs, and organ systems—working perfectly together to keep that individual alive. |
respritroy system | Nose and nasal cavity –
Mouth –
Pharynx (throat) –
Larynx (voice box) –
The lower respiratory tract primarily handles air conduction and gas exchange:
Trachea (windpipe) –
Bronchi and bronchioles – the trachea divides into right and left bronchi, which branch into smaller bronchioles within the lungs, distributing air to all regions.
Alveoli –
Lungs –
Diaphragm and intercostal muscles – primary muscles for breathing; they create pressure differences to draw air into and out of the lungs.
Additional Components
Respiratory muscles – besides the diaphragm and intercostal muscles, accessory muscles aid in deep breathing.
Capillaries and blood vessels – transport oxygen and carbon dioxide between alveoli and the rest of the body. |
