Answers
Answer:
1.“Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”
2.The following raw materials are required for photosynthesis: i. Carbon Dioxide: Plants get CO2 from atmosphere through stomata. ... Sunlight: Sunlight, which is absorbed by the chlorophyll and other green parts of the plant.
3.Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.
4.Thus, a plant absorbs water and minerals from soil through roots and transport it other parts like stem, leaves, flowers etc. It is through two kinds of elements of xylem tissue called, xylem vessels and tracheid that water and minerals move from roots of a plant to its leaves.
5.A nephron is the basic unit of structure in the kidney. A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. ... The glomerulus is the specialized configuration of capillaries within the nephron that make kidneys possible.
Answer:
autotrophic njtrition is the nutrition produced by an organism by themselves
heterotrophic nutrition is depending eithdr directly or indkrectly on plants
autotrophic nutrition sunlight is ncessary. it maens that food is prepared at day time but in heterotrophic nutrition food can be able at any time
they are at the primry level pf food chain but heterotrophic nutrition have secondary and tertiary level
all green plants and algae are the exples for autotrophic
all animals are heterotrophic
plants get raw materials
sunlight from sun which is abindant during day time
water from the soil which is also came from rain
minerals from soil particles
chlorophyll which is present in the leaves of a plant
Carbon dioxide from atmosphere
aerobic respiration is done in presence of oxygen
anaerobic is done in absence of oxygen
in areobic complete oxidation of glucose takes place
in anaerobic glucose is incompletely oxidised
aerobic occurs in plant and animal cells
anaerobic occurs in anaerobic bacteria and human muscles
energy linerated is 38atp
in anaerobic energu liberated is only two atps
water and minerals are transported with the help of special tissue called xylem which is water conducting tissue in plants. xylem does this activity with the suction pressure mainly due to transportation process. when the water evaporates due to transportation process there is. a suction pressure occurs due to the pull..
structure:
nephrons are filtration units of kidney. it contains of tubule, boemans capsule loop of henle, etc
draw the figure
- functions- the bloood entrrs to the renal artery which branches into many cappilalries whicj os brancjed with Bowman's capsule. the filtrate is nle passed to glomerulus. from glomerulas the the filtrate moves foen to proximal tubule
