Question 32

why the 5 kingdoms

Answer 32

because organisms can be classified into groups by the features they share

Question 33

plantea

Answer 33

- multicellular - have cellulose cell walls - have nucleus - have chlorophyll - asexual - are autotrophs (make own food) - bamboos, algae, flowers

Question 34

Animalia

Answer 34

- multicellular - don't have cell walls - have nucleus - don't have chlorophyll - sexual - are heterotrophs -food from oragnism - humans, giraffes, birds

Question 35

fungi

Answer 35

- normally multicellular - have cell walls but not cellulose - have nucleus - don't have chlorophyll - both asexual and sexual - both autotrophs and heterotrophs - mushrooms, mold, yeast
