Question 1
The image shows a section through a specialised plant cell. Removed for copyright reasons
Question 1(a)
Identify structure X .
Golgi (apparatus/body) /vesicles; Do not allow vacuoles
Question 1(b)
State one function of structure X .
modifying/sorting/packaging protein/lipid/polysaccharides OR creation of lysosomes; E.g. proteins, lipids, polysaccharide If vesicles are given for 1a, allow transport of protein/lipid/polysaccharides 1 max
Question 1
The micrograph shows a buttercup (Ranunculus bulbosus) stem in transverse section. Region T has been highlighted to show more detail.
Question 1(a)
In the right-hand box, draw a labelled plan diagram of region T to show the distribution of tissues.
a. vascular bundle; b. xylem OR phloem; c. epidermis; d. cortex; Award one mark for properly labelled tissue and drawn in correct proportion/ shape. Note that a plan diagram is needed. Do not accept diagrams with cells indicated. 3 max
Question 1
The micrograph is an image of human cheek cells viewed with a light microscope.
Question 1(c)
The electron micrograph shows part of an animal cell. Outline the functions of Y and Z in the cell.
a. Y/(mitochondrion) releases ATP/carries out aerobic/cellular respiration; b. Z/(Golgi apparatus) packages/modifies proteins/carbohydrates/lipids / makes lysosomes/vesicles; a. Accept produces ATP / Krebs cycle. Accept correct function for Y/Z, even if incorrect organelle name is given. Do not accept packages substances/molecules/products - too vague. 2 max
Question 2
The electron micrograph shows part of a cell. Which organelle is the site of aerobic respiration?
C
Question 2
What function is performed by the part of the cell shown in the electron micrograph? A. Locomotion B. Synthesis of proteins C. Movement of chromosomes D. Breakdown of cellular organelles
B
Question 2
The image shows an electron micrograph of a cell. Which organelles correspond to the labels in the electron micrograph of this cell? A. secretory vesicles | Golgi apparatus | mitochondria B. mitochondria | Golgi apparatus | secretory vesicles C. secretory vesicles | rough endoplasmic reticulum | mitochondria D. mitochondria | rough endoplasmic reticulum | secretory vesicles
C
Question 2
The diagram summarizes the production and secretion of digestive enzymes in an exocrine gland cell of the pancreas. Which cell organelle is involved at Y ? Rough endoplasmic reticulum Golgi apparatus Lysosome Ribosome
B
Question 3
The image shows an electron micrograph of pancreatic exocrine cells. What is the role of the vesicles shown in the micrograph? A. To transport hormones between the rough endoplasmic reticulum and the Golgi apparatus B. To store glycogen when blood glucose levels are high C. To move enzymes out of the cell by exocytosis D. To digest cellulose
C
Question 3
What is the function of the Golgi apparatus? A. Transport of lipids B. Synthesis of polypeptides C. Processing of proteins for secretion D. Generation of most of the cell's supply of ATP
C
Question 4
Which organelle is involved in generating vesicles destined for the cell membrane? A. Golgi apparatus B. Smooth endoplasmic reticulum C. Rough endoplasmic reticulum D. Lysosome
