In this paper, the organelles of an animal cell will be related to the functions or structure of a house. The organelles to be examined are: the nucleus, nuclear envelope, chromatin, nucleolus, vacuole, cell membrane, lysosome, mitochondrion, golgi apparatus, ribosome, and endoplasmic reticulum. ...
Photosynthesis Photosynthesis plays a crucial role in the carbon cycle. Carbon constantly circulates in the earth's ecosystem. In the atmosphere, it exists as colorless, odorless carbon dioxide gas, which is used by plants in the process of photosynthesis. Animals get the carbon stored in plant tissue when they eat and exhale carbon dioxide. ... They are among the leading decomposers of organic matter; breaking down plant and animal remains and wastes into their chemical states, as well as having a critical role in the recycling of minerals and carbon. ...
biology Living things make up the world as we know it. Living things are involved in our life constantly, seeing that we are alive. There are five characteristics that are common to all living things. Living things are made up of one or more cells. Each cell is made up of living matter and is se...
Together they form a very large surface area through which oxygen and carbon dioxide can diffuse. Plants have stomata to allow carbon dioxide to enter the leaf for photosynthesis. Unfortunately for the plant, if stomata are open to allow carbon dioxide into the leaf, they will also allow water vapour to leave. ...
Important Facts the smallest unit of life is the cell instructions for development are contained in DNA collectively, all of the chemical processes in a cell are called metabolism producers often obtain energy from the sun homeostasis refers to the ability to maintain a constant internal environment cells in domains archaea and eubacteria lack nucleii plants are multicellular producers an educated guess might be called a hypothesis science is based on evidence philosophy is not a step in the scientific method an atom is the smallest unit of substance that retains the properties of the subst...
For a long time, no one knew that plants and animals were made of. Then, in the seventeenth century, the microscope was invented. Scientists used the microscope to study plants and animals. When sections of living things were magnified under the microscope, tiny structures could be seen for the ...
More to do with plants, in 1779 Ingenhousz would describe the carbon cycle present in plant respiration! He realized that plants gave off a flammable gas oxygen during the day but carbon dioxide at night leading him to hypothesize when carbondioxide was being released by a plant (Historic Figures 1). ...
