M2: PLANT CELL AND TISSUES Flashcards
smallest living unit
CELL
first saw cells in 1665
ROBERT HOOKE
what did Robert Hooke used to observe cells
CORK
CELL THEORY
- All living things are made of cells
- Cells are the basic unit of structure and function in an organism (basic unit of life)
- Cells come from the reproduction of existing cells (cell division)
In 1838, a German botanist named _______ concluded that all PLANTS WERE MADE OF CELLS . He is a cofounder of the cell theory
MATTHIAS SCHLEIDEN
ENGLISH FATHER OF MICROSCOPY
ROBERT HOOKE
Robert Hooke coined the term “cells” because they look like ____
SMALL MONASTERY ROOMS
In 1839, a German zoologist named ________ concluded that all ANIMLAS WERE MADE OF CELLS. He also cofounded the cell theory
THEODORE SCHWANN
In 1855, a German medical doctor named __________ observed, under the microscope, CELLS DIVIDING. He reasoned that all cells COME FROM OTHER PRE-EXISITING CELLS by cell division
RUDOLPH VIRCHOW
the study of the STRUCTURE and FUNCTION of the cells
CYTOLOGY
two types of cells
PROKARYOTIC
EUKARYOTIC
They have NO TRUE NUCLEUS as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid.
PROKARYOTIC CELLS
a cell that has a MEMBRANE-BOUND NUCELUS and other membrane-bound compartments or sacs, called organelles, which have specialized functions.
EUKARYOTIC CELLS
The word eukaryotic means “_______”
TRUE NUCLEUS
multicellular cells
EUKARYOTIC
basic BUILDING BLOCK OF PLANT LIFE. they carry out all the functions necessary for survival
PLANT CELL
- EUKARYOTIC CELLS
- have a true nucleus along with specialized structures called organelles that carry out different functions
PLANT CELLS
specialized structures are called
ORGANELLES
an OUTER COVERING that PROTECTS the bacterial cell and GIVES IT SHAPE
CELL WALL
it is composed of cellulose and other substances
CELL WALL
what is the main component of the cell wall
CELLULOSE
what are the other substances of cell wall
LIGNIN, SUBERIN, CUTIN
a STRUCTURAL CARBOHYDRATE and considered a COMPLEX SUGAR because it is used in protection and structure
CELL WALL
a JELLY-LIKE substance composed mainly of water that also contains enzymes, salts, cell components, and various organic molecules.
CYTOPLASM
it is present within the cell membrane of ALL CELL TYPES and contains all organelles and cell parts
CYTOPLASM
responsible for GIVING THE CELL ITS SHAPE
CYTOPLASM
where MOST CHEMICAL PROCESSES take place
CYTOPLASM
a NETWORK OF PROTEIN FIBERS that helps to MAINTAIN THE SHAPE of the cell, secures certain organelles in specific positions, allows cytoplasm and vesicles to move within the cell, and enables unicellular organisms to move independently
CYTOSKELETON
involved in the MOVEMENT within the cell
CYTOSKELETON
MAINTAINS CELL SHAPE and help in INTERNAL MOVEMENT and MOTILITY
CYTOSKELETON
two types of fibers within the cytoskeleton
MICROFILAMENTS
MICROTUBULES
move chromosomes during cell division
MICROTUBULES
made up of protein TUBULIN
MICROTUBULES
cytoplasm is also called as
CELL JELLO
made from G-ACTIN protein
MICROFILAMENTS
are the THINNEST of the cytoskeletal fibers and function in moving cellular components.
MICROFILAMENTS
large tubular structures composed of the protein tubulin
MICROTUBULES
part of the structure of CILIA & FLAGELLA
MICROTUBULES
small, SPHERICAL ORGANELLES with specialized enzyme and are bound by single membrane
MICROBODIES
3 MICROBODIES
PEROXISOME
GLYOXISOME
LYSOSOMES
are long, HAIR-LIKE STRUCTURES that extend from the plasma membrane and are used to MOVE AN ENTIRE CELL
FLAGELLA
In animal cells, the ________ are the cell’s “GARBAGE DISPOSAL.” DIGESTIVE enzymes within the ______ aid the breakdown of proteins, polysaccharides, lipids, nucleic acids, and even worn-out organelles.
LYSOSOME
is a rigid covering that PROTECTS the cell, provides STRUCTURAL SUPPORT, and GIVES SHAPE to the cell.
CELL WALL
Provides STRUCTURE to cell; site of many METABOLIC REACTIONS; medium in which ORGANELLES ARE FOUND
CYTOPLASM
OXIDIZES and BREAKS DOWN FATTY ACIDS and AMINO ACIDS, and DETOXIFIES POISON
PEROXISOMES
DIGESTION of macromolecules; RECYCLING OF WORN-OUT organelles
LYSOSOMES
Maintains cell’s shape, secures organelles in specific positions, allows cytoplasm and vesicles to move within the cell, and enables unicellular organisms to move independently
CYTOSKELETON
PEROXISOME is a membrane-bound packets of _____
OXIDATIVE ENZYME
contain enzymes needed by plants to survive during hot conditions
PEROXISOMES
plant survival during hot conditions
PHOTORESPIRATION
converts FATTY ACIDS TO SUGAR as fuel for respiration
GLYOXISOME
a SIRIES OF INTERCONNECTED MEMBRANOUS TUBULES that collectively modify proteins and synthesize lipids.
ENDOPLASMIC RETICULUM
system of membrane-bound channels visible only under electron microscope
ENDOPLASMIC RETICULUM
the endoplasmic reticulum is only visible under what type of microscope
ELECTRON MICROSCOPE
CONNECTED with the OUTER MEMBRANE of the NUCLEUS
ENDOPLASMIC RETICULUM
transport materials within the cell
ENDOPLASMIC RETICULUM
is so named because the ribosomes attached to its cytoplasmic surface give it a STUDDED appearance when viewed through an electron microscope.
ROUGH ENDOPLASMIC RETICULUM
ribosomes are NOT attached
SMOOTH ER
lipid secretion/storage/synthesis are synthesized
SMOOTH ER
is continuous with the RER but has few or NO RIBOSOMES on its cytoplasmic surface. The ______ functions include SYNTHESIS of carbohydrates, LIPIDS (including phospholipids), and steroid hormones; detoxification of medications and poisons; alcohol metabolism; and storage of calcium ions.
SMOOTH ENDOPLASMIC RETICULUM
ribosomes are attached to
ROUGH ER
PROTEIN synthesis takes place
ROUGH ER
are the CELLULAR STRUCTURE responsible for PROTEIN SYNTHESIS.
RIBOSOMES
these are DENSE GRANULES present in the cytoplasm
RIBOSOMES
INVOLVED in PROTEIN SYNTHESIS
RIBOSOMES
it may be free or attached to the endoplasmic reticulum
RIBOSOMES
anong tinatrabaho ni ribosomes kapag free siya
THE CELL ITSELF
nasan si ribosomes kapag free siya
CYTOSOL

LOCATION
DOUBLE LAYERED organelle of the plant cell
MITOCHONDRIA
are often called the “POWERHOUSES” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main ENERGY-CARRYING molecule.
