types of cells
These cells are tightly attached to one another.
Epithelial Cells
what exactly is an organisms
a plant, animal, bird, insect and even a microbe
what exactly is a prokarya and eukarya
Cells of bacteria are called prokaryotic cells . Cells of animals, plants and fungi are called eukaryotic cells .
what does mitosis do
cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells
what is a food chain
describes how energy and nutrients move through an ecosystem.
These cells are specialized for communication.
Nerve Cells.
what are three types of organisms
producers, consumers and decomposers.
what is the purpose of the prokarya
They play a critical role in the recycling of nutrients by decomposing dead organisms and allowing their nutrients to be re-used
what does meiosis do
reduces the number of chromosomes in gametes
what is a food chain made up of
producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers
These cells are specialized for contraction
Muscle Cells.
what is the most important organism
Bees
what purpose does the eukarya serve
produce energy (ATP) and therefore are called the 'powerhouse of the cell'
what would happen with out meiosis
the number of chromosomes will not remain constant in a species across generations and will be duplicated every time after sexual reproduction
ar food chains important
Food chains are important because they show the intricate relationships in ecosystems.
why are cells important
provide structure and function for all living things, from microorganisms to humans.
why are organisms so important
Microorganisms help to generate oxygen and carbon dioxide, as well as fix atmospheric nitrogen into useable forms for multiple organisms
why do we need prokarya
help us digest our food, produce crucial nutrients, protect us from pathogenic microbes, and help train our immune system to function correctly
what would happen without mitosis
they would not be able to grow and replace worn-out cells.
how does a food chain start
Producers, also known as autotrophs, make their own food.
what is the most important cell
fertilized egg cell or “zygote"
could a human live without organisms
People definitely cannot survive without other species.
why do we need eukarya
energy balance, metabolism, and gene expression.
how does mitosis affect the earth
grow, heal wounds, and replace damaged cells.
what is the most important food chain
Primary producers are important to the whole food chain because they are the original source of energy that is then passed between other organisms
