Document Summary

Motile animals that can move from one place to another. Sessile animals that stay in one place. Individuals of some animals employ more than one feeding strategy www. notesolution. com. Some employ entirely different feeding strategy at different points in their life cycle. they bring water into their bodies by beating the flagella of their specialized feeding cells choanocytes. these choanoflagellates are related to fungi, these groups form a clade known as the opisthokonts. Herbivores animals that eat plants: they often feed on plants without killing the plant, they typically have long, complex guts to accomplish the tasks involved in digesting plants. Jellyfish"s tentacles are covered with specialized cells that contain stinging organelles nematocysts. Omnivores eat both plants and other animals humans. many flatworms are endoparasites to humans and other mammals: parasites that live outside their hosts ectoparasites.

Which of the following is NOT true about the evolution of multicellularity?

Question 9 options:

	Multicellularity arose in the common ancestor of animals and fungi
	Multicellularity likely enabled early aquatic species to escape predation.
	Multicellularity likely arose in a similar way but involving different genes in an ancestor of plants, and an ancestor of animals
	In the common ancestor of the land plants and charophytes, multicellularity likely arose when a cell wall gene developed a "sticky" function
	Multicellularity enabled the evolution of specialized cells.

1. Plants and animals do not share a common multicellular ancestor. These seprate evolutionary events led to different methods of achieving complex multicelularity in these groups. Why do plants and animals differ with regards to their development and how do they differ?

2. Describe the evolutionary trend with regards to alternation of generations in land plants?
