4.1
Biosphere
This is an instrument that makes an enlarged image of a small object.
Microscope
the biochemical and physiological process by which an organism uses food to support its life.
Nutrition
Heterotrophs are organisms that CAN'T make their own food and so must get energy by eating plants and animals to survive.
Heterotroph
Inorganic substances that are found in living and non-living. In living things, this will form very hard structures, such as shells, teeth, and bones
Mineral salts
A thin layer around the cells and some organs, which protects them and regulates the transport of substances entering and exiting the cell.
Cell membrane
living things that make their own food for energy from non-living substances in their environment.
Autotroph
Heterotrophs are organisms that can't make their own food and so must get energy by eating plants and animals to survive. It usually involves exchanging two gases—oxygen and carbon dioxide. The cells take in oxygen and release carbon dioxide.
Respiration
an important nutrient made of microscopic building blocks called amino acids
Protein
A plant cell organelle in which photosynthesis occurs. It contains a green pigment called chlorophyll.
Chloroplast
an organism that mostly eats meat, or the flesh of animals.
Carnivore
All living organisms can detect and respond to environmental changes using their sensory receptors.
Sensitivity
An organic substance found in living things. It is a fatty/ waxy organic compound that stores energy.
Lipid
The area in a cell between the nucleus and the cell membrane. It contains different organelles.
Cytoplasm
an organism that mostly feeds on plants.
Herbivore
the process in which green plants use sunlight to make their own food. This is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals.
Photosynthesis
Nucleic Acid
membrane-bound cell organelles(mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
Mitochondria
an organism that eats BOTH plants AND animals
Omnivore
What is the difference between sexual and asexual reproduction?
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
