please answer fast u will be marked as brainlliest
Answers
Answer:
a)Stomata are tiny openings or pores in plant tissue that allow for gas exchange
b)Chlorophyll is a green photosynthetic pigment found in plants which helps in absorbing sunlight
c)the process of providing or obtaining the food necessary for health and growth.
d)Intestinal villi are tiny, finger-like projections made up of cells that line the entire length of your small intestine. Your villi (villus is the singular, villi is the plural) absorb nutrients from the food you eat
e)the first stomach of a ruminant, which receives food or cud from the oesophagus, partly digests it with the aid of bacteria, and passes it to the reticulum.
F)The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells.

Stomata :
In botany, a stoma, also called a stomate is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.
Chlorophyll :
a green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.
Nutrition :
Nutrition is the science that interprets the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion.
Villi:
Intestinal villi (singular: villus) are small, finger-like projections that extend into the lumen of the small intestine. ... Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption.
Rumen :
the first stomach of a ruminant, which receives food or cud from the oesophagus, partly digests it with the aid of bacteria, and passes it to the reticulum.
Pancreas :
a large gland behind the stomach which secretes digestive enzymes into the duodenum. Embedded in the pancreas are the islets of Langerhans, which secrete into the blood the hormones insulin and glucagon.
