This group includes many kinds of unicellular eukaryotic organisms. Some of these organisms use appendages, such as hair-like cilia or whip-like flagella for moving around.
7.
These are heterotrophic eukaryotic organisms. Some of them use decaying organic material as food and are therefore called saprotrophs.
8.
These include all organisms which are multicellular eukaryotes without cell walls. They are heterotrophs.
12.
These are called the amphibians of the plant kingdom.
14.
The plants of this group bear naked seeds and are usually perennial, evergreen and woody.
15.
These are animals living in water. They show more body design differentiation. There is a cavity in the body.
16.
These animals differ from the fish in the lack of scales, in having mucus glands in the skin, and a three-chambered heart.
17.
This is probably the largest group of animals. These animals are bilaterally symmetrical and segmented.
18.
These animals are cold-blooded, have scales and breathe through lungs.
19.
They have an open circulatory system and kidney-like organs for excretion.
Down:
1.
These organisms do not have a defined nucleus or organelles, nor do any of them show multi-cellular body designs.
2.
Plants that do not have well-differentiated body design fall in this group. The plants in this group are commonly called algae.
3.
The plant body is differentiated into roots, stem and leaves and has specialised tissue for the conduction of water and other substances from one part of the plant body to another.
4.
These are warm-blooded animals and have a four-chambered heart. They lay eggs. There is an outside covering of feathers, and two forelimbs are modified for flight.
5.
The body is also bilaterally symmetrical and triploblastic.
6.
These are multicellular eukaryotes with cell walls. They are autotrophs and use chlorophyll for photosynthesis
9.
The body of animals in this group is far more complexly designed than in the two other groups
10.
Animals are also bilaterally symmetrical and triploblastic, but in addition they have a true body cavity.
11.
The seeds develop inside an ovary which is modified to become a fruit
