Macromolecules or large particles are carried across the cell membrane via vesicles or other intracellular structures. Pinocytosis and efflux are the two types of vesicle transport.
<h3>How does a vesicle leave the cell with its cargo?</h3>
Exocytosis is the process by which cells move components from within the cell to the extracellular fluid. Exocytosis occurs when a vesicle's plasma membrane fuses with it, expelling its contents outside the cell.
The Golgi, also known as the Golgi complex, is a flattening, layered organelle that looks like a stack of pancakes. The Golgi body modifies and packages proteins and carbohydrates into lattice vesicles for "exportation" from the cell.

Some activities that cell requires energy may include cell division, active transport, protein synthesis etc.
In human, Cells get their energy by the food we eat. The nutrients in the food breaks down into soluble and simple molecules in stomach and small intestine and it is absorbed through the small intestine and assimilated into the cells, becoming part of it, providing the uses for each type of nutrient. And of course, many of them is the energy source.
Answer:
The correct option is <u><em>A. they evolved from land mammals.</em></u>
Explanation:
The process of evolution explains how closely one organism is to another based on their common ancestors. Scientists believe that those organisms which show many similarities in their structures or functions might have evolved from a common ancestor in the past.
As in the above-mentioned question, scientists have observed that cetaceans lack gills and breath air, this is a property of land mammals. The cetaceans have fin bones which are similar to the limb bones. As limb bones are present in land mammals, hence they cetaceans and land mammals might have common ancestors in the past.
The answer for the question is the Apical meristem.
Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem.
