- 1Unit 2.4 Cell to OrganismScience Br Oussama
- 2Define Multicellular OrganismsLiving things made up of many cells.
- 3What are tissues?Tissues are similar specialised cells working together to complete a specific task.
- 4What are Organs?Tissues are organised into organs.An organ is a structure that contains at least two different types of tissue working together to complete a task.
- 5What are Organ systems?Organs are arranged into organ systems.Organ systems have two or more organs that work together.
- 6How many types of tissues are there?Four
- 7What are the names of those tissues?Epithelial, Connective, Muscle and Nerve tissue
- 8What is Epithelial tissue made up of?It's made up of cells that form surfaces over other organs.
- 9Which organ is best known for its Epithelial tissue?The skin, it has an outer layer of Epithelial tissue called epidermis.
- 10What other parts of the body is covered with epidermis?Inside the mouth, digestive system & the Reproductive system
- 11What does the connective tissue do?It supports and holds together other tissues.
- 12What are some examples of connective tissueFat, Bone, Cartilage, Ligament, and Tendon
- 13What does Ligament do?It hold your bones together at the joints.
- 14What do Tendons do?It joins muscles to bones.
- 15What do Muscle tissues do?They contract, become shorter and fatter.
- 16What do Nerve cells do?They can send e;electrical signals around the body.
- 17What are organs?Tissues are grouped together into organs. Different tissues contribute to the job that the organ has to do.
- 18Name a couple of organs in the human body.Kidney, Heart, Liver and skin.
- 19Which organ is the largest?The skin.
- 20Why does the body need blood?Blood carries nutrients and oxygen to the cells, and carries wastes away from the cells.
- 21What happens in the stomach and small intestine?Food goes through chemical changes so the body can use it.
- 22Explain the Respiratory systemIt gets oxygen from air into your body and gets rid of carbon dioxide.
- 23What is the skeleton system?The skeletons and muscles.
- 24What does the Excretory system do?Gets rid of wastes from the body.
- 25Explain what the Nervous system doesIt sends message from the body to then brain, then from the brain to other parts of body including the muscles.
- 26Explain the Reproductive systemIt creates and transports specialised cells necessary for reproduction. In females, it provides structures and nutrients for development of baby.
- 27What are essential functions for the plantPhotosynthesis, Transport and reproduction
- 28Define the Vascular tissueIts made up of cells that create hollow tubes for the transport of nutrients and other substances in fluid.
- 29Define XylemCells in a plant that carry water from the roots to the rest of the plant
- 30Name the main organs in a plantRoots, Stems and leaves
- 31Define PhotosynthesisThe process used by plants to make food from water and carbon dioxide using energy from the sun.
- 32What carries water from soil to the plant?Roots.
