What do cells and tissues require for survival?
Cells in the human body need nutrients and oxygen to survive.
Most tissues in the body rely on the active transport of blood to supply individual cells with nutrients and oxygen, with the exception of avascular tissues, such as articular cartilage.
For tissues engineered in a laboratory, the same principles hold true..
Where do cells in the human body get their food from?
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
What is the smallest unit of life?
cellThe cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
What living things can do?
Each living thing can Move; Reproduce itself; and is Sensitive to the world around it. Each one can also Grow; Respire (release energy); Excrete (get rid of waste from its body); and get or make food by a process called Nutrition.
What is short life process?
Biological life processes are the activities that an organism performs to survive. These are the basic activities that have to be done in order for an organism to survive- These include nutrition, excretion, respiration, movement, reproduction, response to external stimuli, growth and movement.
What are 3 things your cells make in order to maintain life?
All living organisms:Need energy to carry out life processes.Are composed of one or more cells.Respond to their environment.Grow and reproduce.Maintain a stable internal environment.
How do cells get the materials they need to survive?
During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function. They release the carbon dioxide into the air as a waste product.

What is the life process?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. … In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion.
What are the basic needs of all cells?
Most living things need water, food, and air. Some living things consist of a single cell. Like familiar organisms, they need food, water, and air; a way to dispose of waste; and an environment they can live in.
What does every living cell need?
Every cell in your body needs oxygen to help it metabolize (burn) the nutrients released from food for energy. You also know that you need food.
