VERIFIED ANSWERS
Determinate Growth - Answer-maximum size genetically determined (growth stops after
a time, usually cannot heal/regrow, leaves, flowers, fruits)
/.Indeterminate Growth - Answer-no maximum size genetically (able to keep growing
through life and can usually can heal/regrow, roots and stems)
/.Cell Theory - Answer-All plants and animals are made of cells
cell is the basic unit of life,
cells arise by reproduction from previous cells
/.All cells contain what components? - Answer-1. Plasma Membrane
2. Cytoplasm
3. DNA
4. Ribosomes
/.Plasma Membrane - Answer-serves as a barrier between cell and environment
controls the passage of organic molecules, ions, water, oxygen, and cellular waste
/.Cytoplasm - Answer-provides the structure for different components of the cell
comprised of organelles suspended in a gel-like material(cytosol) and protein threads
(cytoskeleton)
/.DNA-Nucleus - Answer-directs the synthesis of ribosomes and proteins
stores chromatin (DNA and proteins) and the nucleolus (where ribosomes are made)
separated from the rest of the cell by the nuclear envelope
/.Ribosomes - Answer-structures responsible for protein synthesis
(not organelles)
recieves instructions from nucleus in the form of mRNA on the specific order of amino
acids to build a given protein
/.Eukaryotic cells include - Answer-endomembrane system
endoplasmic reticulum
golgi apparatus
mitochandria
vesicles and peroxisomes
/.endomembrane system - Answer-modify, packages and transport lipids
, /.vesicles and peroxisomes - Answer-bud off from the endomembrane system as
transport units for diverse materials
/.Endoplasmic Reticulum - Answer-series of interconnected sacs and tubules that
modify proteins and synthesize lipids
/.Golgi apparatus - Answer-series of flattened membranes that recieves proteins and
lipids from the ER, which then sorts tags, packages and distributes
/.Mitochandria - Answer-powerhouse of the cell and site of cellular respiration
makes ATP from glucose and other nutrients
uses oxygen and produces carbon dioxide as waste product
contains its own dna and ribosomes
/.Plant cells unique components - Answer-cell wall
central vacuole
plastids such as the chloroplast
/.Central vacoule - Answer-stores water and can fill much of the cells
regulates water concentration in cell
stores nutrients ions and waste products
surrounded by tonoplast
/.chloroplast - Answer-type of plastids that stores chlorophyll and other pigments for
photosynthesis
contains its own DNA and ribosomes
/.tylakoids - Answer-pigments are stored in interconnected sacs called
/.Grana - Answer-stacks of tylakoids
/.Primary Cell wall - Answer-occurs on the surface of all plants cells
initially deposited ont he surface of middle lamella
composed of cellulose microfibils bundle together
/.Middle Lamella - Answer-thin layer of pectin binding adjacent cells
/.Secondary cell wall - Answer-made of layers deposited inner to primary wall
thicker than primary wall
lignin is deposited together with cellulose-adding rigidity
/.Plasmodesmata - Answer-pores which allow for communication between cells
/.Meristems - Answer-regions of continuous cell division and growth located in different
points of the plant
