Lecture 1

Question 1

Botany is the study of

Answer 1

plants

Question 2

First organisms

Answer 2

heterotrophs – 3.8 billion years ago and consumed on another

Question 3

Heterotrophs consumed

Answer 3

each other in order to gain energy (before photosynthesis)

Question 4

Other/older form of photosynthesis/oxygenic 3.5 billion years ago

Answer 4

conversion of light into chemical energy

sulfur and hydrogen sulfite as terminal redundant and electron donor water is not used

Question 5

Cambian error

Answer 5

life diversified greatly and animals move out of water and into land

Question 6

how many different types of species

Answer 6

400,000

Question 7

how do plants differ from most animals

Answer 7

plants do not have purpose (decision)

plants must survive in their local environment

an individual plant is an indeterminate result of the interaction of genes and environment (plasticity)

Question 8

Plasticity

Answer 8

an individual plant is in-determinante result of interaction of genes and environment

response and adaptation to surroundings

result of interaction of genes the plant contains in its environment

ex: maple trees

Question 9

Answer 9

retain nucleus and membrane bound organelles

Question 10

Multicellular

Answer 10

once did or do perform photosynthesis

Question 11

Cellulose

Answer 11

in cell walls and perform alteration of generation

division of asexual and sexual forms or stages in differ life form

alteration of genes

Question 12

Vacuoles

Answer 12

membrane bound organelles that are filled with fluid containing enzymes, nutrients, and other pigments

Question 13

Alteration of generations

Answer 13

division of asexual and sexual forms or stages in differ life forms

Question 14

Store startch

Answer 14

derived from sugar created by photosynthesis

Question 15

Gametes

Answer 15

all plants have protected by a layer of sterile cells

one layer
