Why watch a plant grow? Plants don’t seem to do anything!

Plants keep us alive

Plants can alter the existence of all other organisms

What is a plant? We usually

recognize plants by Color Structure Location

Scientifically, plants are classified as any organism with the ability to Make food in their

own cells i.e. use inorganic materials to make organic materials

How do plants maintain homeostasis?

Homeostasis is internal balance

04/22/23Plant Watch Unit, Ms. Bruce

Humans maintain homeostasis using their body systems and life functions/processes like

The questions we want to answer are . . . What gives a plant structure and support in the

open world? What do plants actually do to get food? W\hat wastes do plants have and how do they get

rid of it? What gases do plants need to survive and how do

they get and use them? How does a plant move stuff around if it can’t

move itself? How do plants produce more plants? How does a seed grow into a plant or a tree? How do plants know what’s going on around them

and how do they react?

Homework Make a KWL chart for this unit. How is a plant different from an animal? Compare a cactus to a rose to an apple

tree to a pine tree. Why do you think plants have such different structures?

What proof do we have that people need plants as much as we need them? (Think about recycling!)

Homework Cont’d

In some land plants, guard cells are found only on the lower surfaces of the leaves. In some water plants, guard cells are found only on the upper surfaces of the leaves. Explain how guard cells in both land and water plants help maintain homeostasis. In your answer be sure to:

• identify one function regulated by the guard cells in leaves

• explain how guard cells carry out this function • give one possible evolutionary advantage of the

position of the guard cells on the leaves of land plants

A series of investigations was performed on four different plant species. The results of these investigations are recorded in the data table below.

Characteristics of Four Plant Species

Based on these data, which two plant species appear to be most closely related? Support your answer.

Plant species ____________ and __________

What additional information could be gathered to support your answer to the previous question?

State one reason why scientists might want to know if two plant species are closely related.
