A

Dinoflaggelates

14
Q
  • includes all the plants
    – they are eukaryotic, multicellular and
    autotrophic organisms.
A

PLANTAE

15
Q
  • all members are multicellular and have eukaryotic cells.
    – are heterotrophic (they consume other organisms, breathe oxygen, have myocytes, able to move, reproduces sexually and grows from hollow sphere of cells during embryonic development)
A

ANIMALIA

16
Q

holds and protects the cell.

A

CELL MEMBRANE/PLASMA MEMBRANE

16
Q

gelatinous matrix or base material of the nucleus

A

nucleoplasm

16
Q

either embedded or suspended in the nucleoplasm (double helix)

A

chromosomes

17
Q

Three components of nucleus:

A

nucleoplasm
chromosomes
nuclear membrane

17
Q

serves as skin around nucleus which contains holes

A

nuclear membrane

17
Q

primary difference between eukaryotic and prokaryotic cells

A

NUCLEUS

18
Q

semifluid portion of the cytoplasm

A

cytosol

18
Q
  • where tRNA molecule is manufactured
    – it exits the nucleus and becomes part of the
    structure of ribosomes
A

nucleolus

19
Q

semifluid, gelatinous, nutrient matrix which houses important organelles in the cell like the golgi apparatus, ER, mitochondria, vacuoles

A

CYTOPLASM

20
Q
  • highly convoluted(very twisted) system of membranes that are interconnected and arranged to form a transport network of tubules and flattened sacs within the cytoplasm.
    – produces proteins for the rest of the cell to function.
A

ENDOPLASMIC RETICULUM

20
Q

has ribosomes hence it being rough which attaches to the outer surface of the membrane

A

Rough ER

21
Q

not attached to the membrane

A
