Plant cells may generate energy through which of the following?
anaerobic respiration |
|
all of these |
|
photosynthesis |
|
aerobic respiration |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
Which of the following is true about species groups?
a population is made up of a group of communities |
|
a biome is a made up of a group of biospheres |
|
an ecosystem is a biological population |
|
a community is made up of a group of populations |
A population is a group of organisms of the same species who live in the same area at the same time. A community is a group of populations living and interacting with each other in an area.
A large naturally occurring community of flora and fauna occupying a major habitat is:
a population |
|
a food chain |
|
a biome |
|
a community |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
Which of these is not a component of blood?
plasma |
|
white blood cells |
|
marrow |
|
red blood cells |
Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
mitochondria |
|
oxygen |
|
sugar |
|
water |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
