vascular tissue
The functions of this tissue is to transport water, minerals, and sugars to different parts of the plant.
How is vascular tissue structure is adapted to its function?
The tissue is made of Xylem and Phloem. Xylem tissue transport water and minerals upwards and throughout the plant. This tissue is made of tracheids and vessels have pores and pipelines that allows minerals and water to be conducted from one tube to the other.
The phloem tissue transport dissolved minerals. It has sieves cells and tubes with numerous pores that allow substances to be with cells. sieveexcahngedadajacent
The 3 reasons plants and propagated asexually are:
1. To preserve the genetic characteristics of a particular plant
2. Propagate plants it do not produce viable seeds for example: (bananas, pineapple, seedless grape etc.)
3. Produce seed that is difficult to germinate or it has a very short.

Answer:
Chloroplast and mitochondria
Explanation:
Chloroplasts are organelles present only in plant cells and algae in regions that become illuminated. They are green in color due to the presence of chlorophyll and are responsible for photosynthesis. Chloroplasts produce ATP in the presence of sunlight and therefore the heaviest fractions should contain these organelles.
Mitochondria are cellular organelles related to the process of cellular respiration. They are often referred to as “powerhouses” of cells because, through the cellular respiration process, a large amount of ATP is generated. Mitochondria do not need light to produce ATP, so it is likely that these organelles are present in the lightest fractions.
Answer:
The answer is:
D. the radiation of herbivores such as grazing animals
Explanation:
Oligocene and Miocene Epochs:
- The Oligocene epoch is characterized by temperate and subtropical climatic conditions which favored the expansion of grasses and reduced forest cover.
- The Miocene epoch, which succeeded the Oligocene era, is attributed to changes in global circulation due to global warming of the climate followed by global cooling towards the end.
The Oligocence and Miocene epoch are both attributed to the expansion of grasslands and savannah. Both eras marked rapid and drastic evolutionary changes in grazing mammals and herbivores. Diverse groups of grazing mammals lived throughout these eras. For example, the largest herbivore and land mammal of all time, <em>Indricotherium</em> (a sort of giant hornless rhinoceros), was present in the Oligocene era.
Similarly, the Oligocene era in North America favored the rapid radiation of primitive horses.
