Question

plants and animals are multicellular organisms? how are multicellular organisms different than unicellular organisms? 1. multicellular organisms are composed of specialized cells that perform specific functions within the organism 2. multicellular organisms are made of larger cells than unicellular organisms 3. multicellular organisms can exchange dna by horizontal gene transfer 4. multicellular organisms have organelles in each cell that perform functions within each cell (a) 1 only (b) 1 and 2 (c) 1, 2 and 3 (d) 1, 2, 3 and 4

Explanation:

1. Multicellular organisms have specialized cells for specific functions. This is a key difference from unicellular organisms which are a single - cell performing all life functions.
2. Cell size is not a defining difference between multi - and uni - cellular organisms. Some unicellular organisms can have large cells.
3. Horizontal gene transfer is not unique to multicellular organisms and is more common in prokaryotes (unicellular in many cases).
4. Both unicellular and multicellular organisms have organelles in their cells to perform functions.

Answer:

A. 1 only
