Q

What tissues provides the main structural support of the plant?

A

Sclerenchyma

19
Q

How are the cell walls of the ground tissue Sclerenchyma?

A

Very thick

20
Q

Collenchyma provides extra support to the plant, especially in places where

A

The plant is growing

21
Q

How are the cell walls of the ground tissue Collenchyma?

A

Irregular

22
Q

What is the function of the ground tissue Parenchyma?

A

It acts as “filler” tissue and make up the bulk of the ground

23
Q

How are the cell walls of the ground tissue Parenchyma?

A

The thinnest of all ground tissue

24
Q

What are the transport tissues within plants?

A

Phloem and xylem

25
Q

What does Phloem transport?

A

Sugar

26
Q

What does Xylem transport?

A

Water

27
Q

Charles’ Law states that

A

Volume and temperature are directly related

28
Q

What are Bryophytes?

A

Small and short nonvascular plants that grow horizontally

29
Q

Do Bryophytes have roots?

A

No

30
Q

What are examples of Bryophytes?

A

Mosses, hornworts and liverworts

31
Q

What are rhizoids?

A

Small hair-like projections, which help in water absorption and provide minor anchorage

32
Q

The latent phase of a twitch contraction describes the period where

A

AP spreads over sarcolemma and down the T-tubule

33
Q

What happens once AP goes down T-Tubule?

A

The sarcoplasmic reticulum releases calcium into the sarcoplasma

34
Q

Tension in the muscles decreases during the

A

Relaxation phase

35
Q

The relaxation phase is when the sarcoplasmic reticulum

A

Pumps Ca2+ into itself

The H-zones begin to shrink and myosin binding sites are revealed in the

A

Contraction phase

What secretes calcitonin?

A

The parafollicular cells of the thyroid

42
Q

What does LH stimulate?

A

Ovulation

43
Q

Corpus luteum produces the

A

Female sex hormones

44
Q

The ΔH°rxn is negative, so the reaction is
