Textbook Question
Chapter 46, Problem 4A
How can osteocytes remain alive within bone?
a. Bones are composed of only dead or dormant cells.
b. Haversian canals are bone structures that contain blood vessels that provide materials for the osteocytes.
c. Osteocytes have membrane extensions that protrude from bone and allow them to exchange materials with the surrounding fluids.
d. Bones are hollow in the middle and the low pressure there draws fluid from the blood that nourishes the osteocytes.

Apart from food, plants need other nutrients like water and minerals.
Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair.
Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants.
7 Where else can plants obtain their nitrogen from?
Plants make their own nitrogen.
B Plants get it from animals.
Plants get it from the soil.
D
Plants have special structures to break down
atmospheric nitrogen.

- Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
