Organs _____.
maksim [4K]

Answer:

perform functions that tissues cannot carry out on their own

Explanation:

In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.

A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.

cooperation

Explanation:

Cooperation occurs when living things of different species work together to benefit themselves. The interaction between a bee and a flower is a symbiotic relationship. A symbiotic relationship between two living things is one in which at least one of the parties benefits. The relationship between the bee and the flower is a mutual one because both parties benefit.

While the pollen and nectar serve as food for the bees, the spread of the pollen to other plants assist in the reproduction process.
