Anatomy Of Flowering Plants Flashcards
Father of plant anatomy is
N.Grew.
Wrote a book titled “The anatomy of plants”
Which meristem is responsible for increase in length?
Apical meristem
Which meristem is responsible for increase in girth/thickness?
Lateral meristem.
Meristem responsible for increase in length if stems of grasses and equisetum is?
Intercallery meristem.
Simple permanent tissue is one made of
Same type of cells.
👉🏻parenchyma
👉🏻collenchyma
Complex permanent tissue is made of
Different type of cells.
👉🏻xylem
👉🏻phloem
Which one is an embryonic meristem 1️⃣promeristem 2️⃣1 °-meristem 3️⃣2 °-meristem 4️⃣plate meristem
Promeristem.
1 °-meristem originates from
Promeristem. # it gives rise to 2 ° meristem. #for example intra-fascicular meristem
Give examples of 2 ° meristem
Inter-fascicular cambium.
Cork cambium.
Cambium in dicots.
Cells divide anti-clinally in
1️⃣Rib/file meristem
2️⃣Plate meristem
3️⃣Mass meristem
Rib/file meristem .
*Helps in formation of lateral roots.
Cells divide periclinally in plate meristem. (T/F)
True.
Cells divide periclinally( in a plane ⊥ to another) in plate meristem.
In mass meristem cells divide 1️⃣Periclinally 2️⃣Anti-clinally 3️⃣Both periclinally and anticlinally 4️⃣Do not divide
Both periclinally and anti-clinally.
Longest cells in plant body are
Fibres.
Sclerieds are found in
In fruit walls of nuts.
Seed coat of legumes.
Leaves of tea.
Coir of coconut is a true fibre. Why?
Bcz its lignified.
Short fibres are called 1️⃣Fuzz 2️⃣Lint 3️⃣Perivascular fibres 4️⃣Libriform fibres
Fuzz
Lint is 1️⃣Long fibre 2️⃣Not true fibre 3️⃣Non lignified 4️⃣Used in cloth making
All of these.
Lint is a long fibre, non lignified, therefore not true and is used in cloth making.
Xylary fibres are 1️⃣In xylem 2️⃣Hard fibres 3️⃣Can’t be knitted 4️⃣Not more useful
All of these.
Xylary fibres are found in xylem, are hard and this can’t be knitted therefore not much useful.
Bast fibres are 1️⃣Commercial fibres 2️⃣Phloem fibres 3️⃣Can be knitted 4️⃣Have great economic value.
All of these.
Bast (phloem) fibres are commercial fibres that can be knitted, this have great economic value.
Which of these are living mechanical tissue: 1️⃣Parenchyma 2️⃣Collenchyma 3️⃣Sclernchyma 4️⃣N.O.T
Parenchyma and collenchyma are living mechanical tissue.
Sclernchyma is DEAD mechanical tissue.
Thick and lignified cell wall is found in Sclernchyma .
T/F
True
Cells are thickened at corners due to cellulose, hemicellulose, pectin deposition, in which simple permanent tissue?
Collenchyma
Cells of which simple permanent tissue have no secondary depositions?
Parenchyma
Collenchyma is found in
A) Most of the dicots.
B) Not in roots and monocots.
Both are correct.
Collenchyma is found in most of the dicots but NOT in roots and monocots.
