Answer 6

the science of classifying and naming plants

Question 7

Rules for naming plants set by the International Board of Plant Nomenclature true or false

Answer 7

Answer 8

no lo olvides!

Question 9

Plants are multicellular eukaryotes or prokaryotes?
With membrane-bound organelles and other membrane-enclosed organelles?

True or false

Answer 9

Eukaryotes

True

Question 10

Characteristics of cell wall

Answer 10

Rigid boundary outside of the plasma membrane
Made of cellulose
Provides structural support and protection

Question 11

Characteristics of chloroplasts

Answer 11

Contain DNA and chlorophyll (green pigment)

Sites of photosynthesis

Question 12

Characteristics of vacuoles

Answer 12

Contains a liquid called sap
With dissolved substances, like sugars, minerals and amino acids
Storage regions of the cell
Undesirable compounds
Helps to regulate water pressure 
Maintains cell rigidity

Question 13

Hola recuerden checar rápidamente la función de otros organelos jeje

Answer 13

Energía, formar proteínas, respiración celular, etc

Question 14

What is plasmodesmata?

Answer 14

Tubular extensions of the plasma membrane that span the cell wall to connect to neighboring cells
The connected structure is called the symplast
Solute transportation through plasmodesma is known as symplastic transport

Question 15

Parenchyma tissue
Collenchyma tissue
Sclerenchyma tissue
are part of the vascular tissues true or false

Answer 15

False, they are part of ground tissues. vascular tissues include Xylem and Phloem
(by which water and nutrients are transported throughout the plant)

Question 16

Xylem and Pholem functions:

Answer 16

X:Conducts water and dissolved nutrient materials from the roots to the stems and leaves & Provides structural support

P:Conducts food materials (carbohydrates formed in photosynthesis) & Provide structural support

Question 17

Type of tissue known as “Skin of the plant”
Responsible for protecting the plant by providing a protective covering over plant parts & prevents water loss (by secreting a waxy substance)

Answer 17

Plant dermal tissue

Question 18

Epidermus tissue is composed of ____ cells with scattered guard cells (allow for gas exchange) and outgrowths called ____
Responsible for supporting the plant and preventing water loss

Answer 18

parenchyma

trichomes

Question 19

all tissues that are neither dermal nor vascular
Makes up much of the interior of a plant
Responsible for photosynthesis, storage of nutrients/water and support
3 basic types (parenchyma, collenchyma & sclerenchyma):
Divided based on nature of cell wall

Answer 19

Plant ground tissues

Question 20

parenchyma, collenchyma & sclerenchyma functions

Answer 20

P: Fleshy/succulent (soft) parts of plants contain parenchyma, Function in photosynthesis, storage & secretion

C:Mechanical support system of plants, Form strengthening tissues

S:Provides the main structural support to a plant

Two types of sclerenchyma cells:
Sclerids - short, cubical cells, which are hard/inflexible (found in the shells of nuts and in the pits of stony fruits)

Fibers - long, tapered cells that are more elastic (often occur in patches, found in the inner bark of flowering plants)
